map-codebase
Analyze codebase with parallel Explore agents to produce .planning/codebase/ documents. Use for brownfield project onboarding, refreshing codebase understanding after significant changes, before major refactoring, when onboarding to unfamiliar codebases, or when asked to understand codebase or analyze project structure. Creates structured documentation of stack, architecture, structure, conventions, testing, integrations, and concerns.
npx skills add majiayu000/claude-skill-registry --skill map-codebase-philoserf-claude-code-setup-2 --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.

Results are structured documents in `.planning/` that provide a comprehensive map of the codebase state. **Core Output** (always generated): - `STACK.md` — Languages, frameworks, key dependencies - `ARCHITECTURE.md` — Sys

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill map-codebase-philoserf-claude-code-setup-2 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
